java - GenericJDBCException catched by wrong part of the try/catch block -

i have block of code:

        } catch (hibernateexception e) {          loginanswer = new logincustomerareaanswer(999);          //this function use error code save inside loginanswer         this.logop.error(logsutilities.logexception(e, "hibernateexception"));       } catch (exception e) {          loginanswer = new logincustomerareaanswer(997);          //this function use error code save inside loginanswer         this.logop.error(logsutilities.logexception(e, "exception"));       } {         return loginanswer;     } 

as can see, catch first hibernateexception type exception , generic exception.

but when log file, when have org.hibernate.exception.genericjdbcexception exception catched generic exception!

why?, genericjdbcexception not "a son" of hibernateexception? not have catched hibernateexception??

this example of log file

2013-05-21 11:01:02 [level: error]*** exception: error code: 997 - not open hibernate session transaction; nested exception org.hibernate.exception.genericjdbcexception: cannot open connection 

i lost this, can me?

most caught spring exception:

org.springframework.transaction.cannotcreatetransactionexception: not open hibernate session transaction; nested exception org.hibernate.exception.genericjdbcexception: cannot open connection
